Don't see HOU taking Clingan honestly, unless they plan on trading Sengun (doubtful). Playing them together would draw Sengun away from the basket in PnR, which is the last thing HOU wants. He already struggles at the 5 as is. They would then have 2 guys who don't excel against PnR on the floor at the same time. That's just not a great pairing imo, unless they plan on using Clingan off the bench (doubtful). Would be surprised if the Rockets went that route.
Think they're much more likely to draft FVV's replacement, whether it be Topic, Reed, or Dilly. The first two make more sense in terms of fit, as Dilly is ball-dominant and you don't want to take the ball out of Jalen Green's hands and have him just standing around in the corner. Remember, Green went off this year after Sengun went down with his injury and he was able to have the ball in his hands a lot more. He finally looked like the elite prospect they drafted 2nd Overall. Doubt they want to stunt that with Dilly. Topic or Sheppard make way more sense imo. But who knows, who they draft will determine the rest of the lottery cause the draft starts at the 3rd Pick this year imo.
